Animals as small and soft as tardigrades seldom have legs and almost never bother walking. But a new study finds that water bears propel themselves through sediment and soil on eight stubby legs, in a manner resembling that of insects 500,000 times their size.
Scientists have launched an ambitious effort to produce high-quality reference genomes for all vertebrate species, from mammals to birds and reptiles. The result could be discoveries with implications for animal conservation as well as human health and disease.
Unlike most humans, bats are naturally resistant to coronavirus infection. Researchers are now searching their genomes for clues that might explain why SARS-CoV-2 can cause devastating disease in our own species.
How do primitive cells “know” where to go during development? Scientists studying the fish equivalent of inner-ear hair cells have shown that biochemical and mechanical cues work together to orchestrate a highly complex arrangement.
A common birthplace of new genes, the male testes are a hotspot for biological innovation. Within these organs, scientists have found a trove of virgin genetic sequences—and a better understanding of how evolution moves forward.
Navigating fruit flies do not have the luxury of GPS, but they do have a kind of neural compass. In a new study, researchers found that the animals decide which way to turn by comparing this internal compass needle to a fixed goal.
